nppucatinniea lieg-11ste, 1ere. seiarnmiagsea `Be it flcnown 'that I, Brzlqacitien of 'the .'United States, 'and a resident 'of Sioux 'Oity, in the comity lof WVoodbury and State 'of Iowa, have invented certain new and vuseful Imp'rcweine'rrts vin HdgeO-ilers, of which the following is a specification.;

The present invention yrelates to l'rubbing and 'oiling means for animals.

l The invention has for its prima-ry object the production of an improved `device against which hogs may rub, and embodying 'certain novel features of construction whereby the animals will cover those 4portions-'of their lbodies which come in "contact with the device, with cil, to lailfleviate irri-tation land eliminate vermin.

-Andther 'object 'of the invention is the' -production 'of lan improved 'hog-'oiler "elnbodying certain lnovel features wherein `the cost of construction and yoperation are reduced to lthe minimum.

"A further `object of "the invention is the production of a hog-oiler 'embodying 'certain novel features 'of construction Iand,*arra-I'l-gei of this application and in which llike characters 4of reference indicate corresponding parts throughut the several views, of which,-

Figure 1 is `a side elevation of fa hog-cider constructed in accordance with the invention, Fig. 2 is a longitudinal section of the same; Fig. 3 is an end elevation of the same mounted upon a platform; Fig. 4 is a central transverse section of the trough; and Fig. 5 is an enlarged vertical transverse section of one of the bearings.

Although I have illustrated and hereinafter described the preferred embodiment of the invention, I would not be understood as being limited to the specific structure chosen for illustration, for various alterations and modifications, in the vdetails ofconstru'ction and larrangeinent of parte, 'may be imade without departing from'the spirit'an'd scope of i-the'invent-ion as defined in the 'appended claims.

V fltefelrringnow to thei illustrations, v5 is an oil-receptacle preferably semi-ellipsoidal in general contour,'a-nd formed integrally with two pairs of -base blocks, f6, vdisposed on o'p'- posite sides yof the :transverse axis of the trough, each lpai-r being 'arranged gtransversely to the trough. The said blocks rest upon bara/7', :prov-idedwith feet, 8, 'adapted llo be bolted, `or otherwise secured to a 4pla-tform,;9. Thebars'are secured to the yblocks bybolts, 10, which pass through the bars and are threaded into ,the fb'locks.

, rlh'e center o-f y'the bottom of the trough is provided with 'a cupped depression, 11, -fo'r the reception'of sediment. The de-pression communicates with 'an 'outlet "opening, 12, whereby the sediment a may be conveniently removed fromv the trough'. rlhe `opening is normally closed v'by a threaded plug, '13.

A,The trough incloses the lower portion of @horizontal roller 14, formed with helically disposed peripheral ribs, 'or vanes, 15, dis'- posed at a Isharp "angle to the vanis of the roller, that "is, 'an vanfgle -of 45 d'egrees,*or less. T-he ends 'of kthe roller are provided with conoidal journals, 16, inclosed by Suitable bearings at the ends of the trough, which rotatably support the rol-ler in spaced rela'- tiofn to the trough.V

The roller is preferably a hollow ellipsoid having helical peripheral ribs, 15, and annular rows of studs, or projections, 17, on its 'end portions. The roller is'cast in halves, the ineeting plane of which is transverse'to the 'a'Xis of the roller. The halves 'of the roller are secured by a rod, 18, which protrudes through the journals, 16, of the roller land lconical nuts, 19, threaded on its ends and into rm engagement with the journals, to secure the roller halves and form the apeXes of the journals.

The bearings each include a plate, 20, which conforms to the shape of, and is bolted or otherwise secured to the end of the trough, and is formed with ears, 21, curved partially around the journals. The plate is also formed with a concave flange, 22, which supports thejournal. The inner side of the ears, 21, may be provided with shoulders, 23, which rest on the edge ofthe trough.

The contiguous edges of the halves of the roller are provided with notches, preferably semi-circular, and the notches of each half register, respectively, with thenotches ofthe other half, to provide the perforations, 24.

The upper edges of the intermediate'portions of the sides of the trough, are cut downwardly, as aty 25,' in order that the sides of the roller may be easily engaged by the animals.

In yoperation oil'f'of any suitable kind, beingfirst placed 'in' the trough, enters the roller throughthe perforations, 24, and as the roller is turned, `by the hog rubbing thereagainst, the roller is coated with the oil and thus communicated tothe body of the ani- The purpose of the helicalvanes is manifold. They afford a very attractive surface for the animal to rub; they serve toy lift the oil when the roller is revolved; and also coact `with the body oftheanimal to turn the roller, either whenthe rubbing is vertical or horizontal, inasmuch as the fvanes are inclined at a sharp angle to the roller axis.

When rotation of the roller is discontinued the oil remaining on the surface thereof, drains from the helical ribs, between the studs and thenceinto the receptacle, and a portion of the oil Hows between the ears, 2l, and .covers the journals.

It is evident that the conical projections on the ends of the roller, which protrude through the bearings, affordlconvenientv and attractive parts against-which the animals rub and oil their ears, and other portions of their body, whichare not easily placed in Copies of this patent may be lobtained for ingscomprising plates on the receptacle hav-v ing upright ears on opposite sides of and curved partly over the journals.

4. A hog-oiler comprising an oil receptacle an ellipsoidal roller therein, having helically-'inclined peripheral ribs inclined at an acute angle to the roller axis, conical journals on the ends of the roller, and bearings on the receptacle to support the journals, the Y journals being extended a distance'through the bearings.

5.' A hog-oiler comprising an oil receptacle, an ellipsoidal roller therein having inclined peripheral ribs inclinedy at an acute angle to the roller axis, said roller comprising duplicate abuttingv halves, the meeting faces-of the halves being transverse to the roller axis, conoidal vjournals on the ends of' theroller, a rod extending axially through the roller, conicalnuts ythreaded on the ends of the rod to secure the halves, eachv to the other, and'form apexes' on .the journals, and bearings mounted on the receptacle to support the journals, the apexes being extended through the bearings.

6. A hog-oiler comprising an oil receptacle, an ellipsoidal roller therein having helically-inclined peripheral ribs inclined at an acute angle to the roller axis, said roller comprising duplicate abutting halves the meeting faces of the halves beingl transverse to the roller axis, conoidal journals on the ends ofl the roller, a rod` extending axially through theroller, conical lnuts-threaded on the ends of the rod to secure the halves, each to the other, and form apexes onthe journals, and bearings for the journals comprising plates mountedon the receptacle and having upright ears disposed on opposite sides of and curved. partly over the journals, and concave flanges to support the under sides ofthe journals. f

In testimony, whereof, I have hereunto set my hand this 3rd day of August, 1916.
